WASHER-PLACING APPARATUS.

Application fil To all whom it may concern:

Be it known that 1, CHARLES GARDNER,

the United States, and resident o't Summit and State citizen of Akron,in the county of of Ohio, have invented certain ful Improvements in lparatus, of which the cation.

The invention aims to provide a simple and economical form of apparatusby wh ch the washers may be expeditiously handled and accurately placedon the said invention comprises of construction bination of parts pins,and the the novel features and arrangement and comhereinaiter desorlbedand V particularly defined by the claims appended hereto.

An embodiment oi my invei trated in the accompanying \vh1ch:

Fig. 4 is a detail view. Referring by reference char acters to thisdrawing, the numeral 1 designates the lower section of the heel moldhaving the customary upstanding washer-holding pins 1 to receive andhold the washers 2, which,

as shown, are of somewhat dished form, or

provided wits. an annular ad acent the washer opening.

These mold sections are p dowel pins 3 deflected portion rovided withwhich serve to accurately align the washer-placing device, ashereinafter demy invention for applying a mold having a single heelcavthelatter bewhat i may e or member, washer-segregating llate e tocorrespond to the groups of plate 5, 5*, these openings and permit ireepassage of washers.

Plate 5 is held slidably superposed on plate a in det suitable means sucelongat ed openings l ermined relation thereto by h as dowels 5 engagingin the plate 4, the re.

In the manufacture of curved heel lifts, such as shown in the I. T'. S.heel, the upper ends of the pins are not in the same plane, as shown inFig. 8, and hence the openings 4 cannot be closely juxtaposed to all thepins, and a space is left above some of the pins which permits thewasher to tip as it is released by the sliding action and hence failsometimes to engage the mold pin. To avoid this objection, I providemeans for holding the washers in place in the washer seats until thelatter are fully uncovered and then forcibly ejecting them, wherebytipping of the washers is prevented.

Such means preferably takes the form of a carrying member 6 havingspring pressed plungers 4' provided with concave lower ends 7 and moldpin receiving recesses 7 These plungers are grouped to correspond to theopenings 5 and means are provided by which member 6 may be properly heldrelative to plate 5, such means conveniently taking the form ofshouldered dowels 8 having their reduced upper ends 8 engaging openings6 in member 6.

The plungers 7 are slidably guided in guides or openings 6 of member 6and held against dislodgment therefrom by cotter pins 7 and they areprovided with annular ribs or shoulders 7 between which and the lowersurface of plate 6 compression springs 9 are confined. In using thisejecting means, plate 6 is superposed over plate and aligned therewithby dowels 8 while the washers are held in the seats, plate 6 beingpressed towards plate 5 to compress the springs, and held in suchposition by means of catches 1O engaging detents or keepers 11 carriedby upturned flanges A of plate 5. If now the assembly is applied to aheel mold and plate l is moved to align the openings 46 and 5 thepressure of the plungers will hold the washers against the surface ofplate 4 by reason of their annular engagement, until the openings areperfectly aligned, and thereafter the washers will be projected upon thepins without danger of tipping or deflection, as shown in Fig. 3,

it being understood that the plungers act more rapidly than the force ofgravity.

Having thus described my invention, what I claim is 1. A washer-placingdevice comprising a pair of plate-like members slidably juxtaposed andhaving each a group of washerreceiving openings adapted to be aligned bya relative sliding move ient of the members, means for properlyregistering such members with a heel mold, and means for forciblyexpelling the washers when the openings in such members are brought intoalign ment.

2. A washer-placing device comprising a pair of plate-like membersslidably juxtaposed and having each a group of washerreceiving openingsadapted to be aligned by a relative sliding movement of the members, andmeans for properly registering such members with a heel mold, said meanscom prising aligning do/wel openings in said members, the openings inthe lower member being elongated.

3, A washer-placing device comprising a pair of plate-like membersslidably juxtaposed and having each a group of washerreceiving openingsadapted to be aligned by a relative sliding movement of the members, acarrier member adapted to be removably secured over the upper of saidmembers, and a group of spring plungers sup ported by said carriermember. tioned to correspond to the openings in said upper member.

4-. A washerplacing device comprising a pair of plate-like membersslidably juxtaposed and having each a group of washerreceiving openingsadapted to be aligned by a relative sliding movement of the members, acarrier member adapted to be removably secured over the upper of saidmembers, and agroup of spring plunge-rs supported by said carriermember, and positioned to correspond to the openings in said uppermember, said plungers having annular washercontact portions at theirlower ends.

In testimony whereof, I afiiX my signature.

CHARLES GARDNER.
